Different types of pulley removal tools are available, including jaw-type, pickle-fork-type, threaded rod or bolt pullers. Using the wrong tool can damage the pulley. Specific tools are designed for certain types and sizes of pulleys, and some are designed for specific manufacturers. Task-specific tools are also available for removing power steering and other pump pulleys.
Many pulley removal tools double as installation tools, making one tool capable of two functions for the cost of one tool. There are several different styles and types of pulley removal tools, from jaw-type and pickle-fork-type tools to threaded rod or bolt pullers. The type of pulley removal tool required to remove any given pulley is determined by the type and size of the pulley requiring removal. While many pulley pullers can be used successfully on different sizes and types of pulleys, there are some pullers designed to work exclusively on an individual type and size of pulley and occasionally a single manufacturer’s brand, such as Ford or General pulleys. Motors, for example.
One problem with pulleys is that, for the most part, they are easily damaged if attempted to be removed incorrectly or with the wrong pulley removal tools. For a heavy steel pulley, two, three or even four jaw pulley removal tools are often required for the task of removing a pulley from a shaft. The jaws of this style of tool sit behind the outer edge of the pulley, while an adjustable threaded center bolt sits in the center of the pulley mounting shaft. As the bolt is tightened against the shaft, the puller body and jaws are forced up onto the bolt, effectively separating the pulley from the shaft.
For lighter duty sheaves, another family of sheave removal tools resembling flat steel fitted with a bolt on each side or in the center can be used to evenly distribute the force of the pulling action over the full width of the pulley. the pulley. With the pulley-puller flat body positioned behind the pulley, the pulley-puller bolts are tightened and the pulley-puller flat body is forced up against the pulley face. As the pulley-puller is raised, the pulley is pushed off the shaft. Other pulley removal tools use this same design, however pullers are C-shaped to slide around the shaft.
Some task specific pulley removal tools are used to remove power steering pump pulleys as well as other pump pulleys of similar design. This style of pulley-puller consists of a heavy bolt with a two-piece coupler that slides around a collar on the face of the pulley. With the coupler in place, the bolt is tightened against the pump shaft and the pulley is pressed. These types of pulley removal tools also work to press the pulley back onto the shaft.
